Description

A precipitation hardenable Nickel-Iron-Chromium alloy having outstanding controllable thermoelastic coefficient
characteristics and excellent oxidation resistance in high temperature atmospheres. The alloy can be processed
to have a constant modulus of elasticity at temperatures ranging from -45 to +65oC (-50 to +150oF).
